Comtech VIPERSAT Management System (VMS)

VMS 3.x is a feature-rich, automated bandwidth, capacity, and network management system with an intuitive, user-friendly GUI and higher degree of configuration automation than previous versions. VMS 3.x is designed to enable network administrators and satellite service providers to easily configure their networks and rapidly and effectively respond to network anomalies. Much more than just a network monitor and control platform, VMS 3.x automates the carrier switching and spectrum management processes within the satellite network. These capabilities allow SCPC carriers to be switched automatically based on application, load, or schedule, providing on-demand services and unparalleled space segment savings.

VMS 3.x interfaces with an IP Router Interface Board (IRIB) in the Satellite modem. The IRIB is a powerful microprocessor based input/output (I/O) controller supporting a variety of different I/O port types and containing embedded software to support all of Vipersat’s functionality. Vipersat networks provide IP connectivity between network nodes, offering UDP and TCP/IP connectivity support.

VMS 3.x allows remote terminals to switch from shared (STDMA) mode to dedicated (SCPC) channels. Switches can be initiated in several ways: manually, via schedule, via application, or via load. Under extreme data loads on a remote terminal, automatic switching is performed on the remote giving it higher throughputs during peak traffic times. Applications such as IP voice (VoIP) or video also produce conditions of high or constant loads due to their streaming nature. Through protocol detection circuits in the remote terminals, the modem router initiates automatic switching to achieve reduced latency and increased throughput.

VMS Key Features and Functions

VMS 3.x network management software provides the following features:

Centralized monitor, configuration, and control of ground segment network equipment
Auto detection of new nodes
Detailed event logs can be filtered and/or exported
Report generation
Statistics gathering and alarm processing
Remote client user login and access
Scalable from small to large networks
Multiple access topologies (TDM, STDMA, SCPC)
Automation of space segment capacity
User defined policies for upstream switching
Multiple STDMA return channel configurations
Star and full mesh capabilities using Single Hop On Demand (SHOD)
Multi-Transponder Mode (MTM)
Multi-Satellite Services (MSS)
On-line help and Wizards

VMS 3.x is based on a client/server architectural model, in which a central hub communicates with remote nodes in a star topology. The client/server model provides a number of advantages. The server maintains all databases in a centralized location accessible to all clients. Thus, updates and changes can be made in a single place and distributed globally to all clients.

Through its client/server architecture, VMS 3.x supports centralized management, control, and distribution of data, alarms, and events. It also supports multiple clients and network management user applications and access to all system features simultaneously. The network management system provides complete visibility over the network.

VMS 3.x is completely scalable to manage small or large systems with dozens or even thousands of network elements. The system has been designed to anticipate future growth and allow expandability in all areas. VMS 3.x easily adapts and continues to perform its automated functions when the network configuration is changed or new remote sites are added.

Highlights of VMS 3.x Key Functions include:

Improved network views – users can zoom in to view all components within the entire network or subnet and observe configuration and status.
Increased STDMA functionality – In conjunction with modem IP module firmware upgrades, VMS 3.x allows for greater flexibility in the configurations of the return STDMA channel. STDMA data slot size can be configured as fixed, variable depending on network load, set to a guaranteed information rate (GIR) for each remote, or set to Entry Channel Mode (ECM).
VMS 3.x supports the switching of SCPC connections using the web-based Vipersat Circuit Scheduler (VCS). VCS simplifies the network setup process and enables bandwidth sharing capacity management for a variety of applications including IP video conferencing, news and sporting events, high capacity file transfers, scheduled broadcasts, distance learning, telemedicine, and end of day transactions.
VMS 3.x supports Vipersat External Switching Protocol (VESP). VESP allows third party applications to negotiate SCPC transmission links between any two or more subnets. It provides for selecting a range of required bandwidth, and single-hop options.
Significantly improved spectrum analyzer like view – Users can easily view the entire managed spectrum of the satellite, and then zoom in on individual transponders and circuits within the transponder.
Separate policies for each remote in the network can be enabled for various automatic switches, such as for voice and video applications, as well as manually or scheduled switched connections.
Easier navigation to subnet components – Enables users to easily and quickly view any individual component within their network, allowing for faster configuration and diagnostics.
